Tell Us About Your ProjectWhat a full house renovation covers
The scope of the work in Cascais
Strip-out and structure
Demolition, structural repairs and any wall removals, with the engineering and the Câmara Municipal de Cascais licence in place before work starts.
Electrics, plumbing and insulation
New wiring and a new distribution board, new supply and drainage runs, and insulation and window upgrades, all done while the walls are open.
Kitchen and bathrooms
Fitted and tiled as part of the same programme, so the trades finish in the right order rather than being booked one by one.
Floors, joinery and finishes
Flooring, doors, built-in joinery, plastering and painting, and the final snagging walk-through before handover.
One contractor accountable
A single alvará-verified contractor coordinates the trades, the schedule and the budget under one written contract.
Gated communities, pools and exterior work
Quinta da Marinha and similar developments add their own architecture review on top of the câmara. Villas with pools and gardens need this coordinated with the interior programme.
Typical costs

Typical timeline
How long a full house renovation takes in Cascais
| Scope | Typical duration |
|---|---|
| Full apartment renovation, once permits are in place | 16–30 weeks (4–6 months) |
| Villa renovation with structural work | 8–14 months |
| Permit processing, if structural work is involved | 60–120 days |

Common mistakes
What goes wrong with a full house renovation in Cascais
Starting before the permit is in place
Work beyond the licensed project can lead to fines, stop orders and problems when you sell. Confirm what is licensed before demolition.
Choosing on the lowest price
A low figure on an unscoped full renovation comes back as extras. Compare scope line by line, not the total.
No contingency for hidden conditions
Older Cascais properties reveal rot, damp and wiring surprises once opened. A sound quote includes a contingency and a clear rule for approving extras.
Paying too much upfront
Payments tied to completed stages protect you. Large advance deposits leave you with little leverage.
Verbal-only agreements
Scope, materials, milestones and price belong in a written contract signed before work begins.
Ignoring community approval
Gated developments can require sign-off for external changes and shared services. Confirm with the administration before finalising the design.
How we vet
Every contractor meets the same standard
Alvará de construção, valid construction licence of a class that covers the value of a full renovation, checked against the IMPIC registry before any contractor joins the network.
Civil liability and works insurance, active policies confirmed, with coverage limits noted on file.
Financial and tax standing, company checked for insolvency, registered debt, and tax and social security compliance.
Working English, confirmed before joining, enough to discuss scope, materials, and changes without confusion.
